What is the difference between

this.Loaded += new RoutedEventHandler(MainWindow_Loaded);

and

childWindow.MyEvent += new EventHandler(childWindow_MyEvent);

I assume you want to know what's the difference between Events and Routed Events. These 2 articles might help you:

In short, RoutedEvents are routed. They can bubble up or drill down the visual tree until they hit a handler.

Standard events are just plain direct subscription.
